[SOLVED] OpenGL and SFML 2
« on: February 13, 2011, 03:24:48 pm »
Hi,

I'm currently learning to use openGL with the website's turorial: http://www.sfml-dev.org/tutorials/1.6/window-opengl.php

I've tried to compile window-opengl.cpp, which i downloaded on that page, but any function begining with gl just cant be found by the compiler. Any tips?

thanks

They are not found by the linker, not the compiler. Which means that you have to link to the GL libraries (I can't tell you more without knowing your OS and compiler).

Thank you for answering me that fast.

Actually, i'm using visual c++, my linker contains this:

opengl32.lib
glu32.lib
sfml-main-d.lib
sfml-system-d.lib
sfml-window-d.lib
sfml-graphics-d.lib
sfml-audio-d.lib

and the errors are either "identifier not found" or "identifier not declared"

Ah, so it seems like these are not linker errors after all ;)

Can you please show the exact error messages?

Which version of SFML are you using? If you use 1.6, GL.h should be included automatically by SFML/Window.hpp.

SFML 2, as said in the subject. Maybe not the latest version from the repository though.

Hmm maybe the opengl header isn't available? Like it's not located in Visual Studio or in the Path. Because that's what it looks like.

That may be true, is there something i should do to have OGL working properly, besides having SFML 2?

It seems i have no GL.h on my computer.

EDIT: nevermind, i have gl.h

Normally it just works straight out of the box. Have you tested just including gl.h yourself?

Problem solved.

I had to download glut and add this line:
#include <gl\glut.h>

In SFML2 this is no longer automatic, but there is still a header that helps with portability (GL include paths are not the same across platforms).
Code: [Select]
#include <SFML/OpenGL.hpp>

GLUT includes GL and GLU headers, but you're definitely not using GLUT, so this was a bad solution ;)
